  An embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 shows a riding tractor as an example of a work vehicle. An engine room covered with a bonnet 2 is arranged at the front of the traveling vehicle body 1, and an engine E is mounted therein. The rotational power of the engine E is transmitted to the transmission in the transmission case 43, and the rotational power decelerated by the transmission is transmitted to the front wheels 5 and the rear wheels 6. A driver's seat 8 is installed in the cabin 7 at the rear of the vehicle body, and a steering handle 9 for steering the front wheels 5 and 5 is provided in front of the driver's seat 8.

  In the engine room, a cooling fan 11 is disposed between the engine E and the radiator 10, and the fan shroud 12 is driven to rotate by the driving force of the engine. A radiator bracket 13 for supporting and fixing the radiator 10 is erected in front of the cooling fan 11, and the gaps 14 </ b> L and 14 </ b> R between the radiator bracket 13 and the radiator 10 are inhaled by punching metal. It is covered with possible plates 15, 15.

  The punching metal plate 15 covering the side surface of the gap 14R on one side between the radiator bracket 13 and the radiator 10 has a shape having a step H in the left-right direction with respect to the traveling direction of the vehicle, and maintains rigidity and bolts. It is set as the structure fastened and fixed detachably via.
